We are getting the following exception when running our Xamarin forms app on an actual Android device(tried multiple devices).  The same code works in an Android emulator(GenyMotion) and also on an actual iOS device.

We are using a mongoDB environment that was created during the "Getting Started" process.  We have ensured internet connectivity on the device.

Here is the line that throws the exception:

var mongoClientConnectionString = "mongodb+srv://user:pwd@our instance.mongodb.net";

var mongoUrl = MongoUrl.Create(mongoClientConnectionString);
var mongoClientSettings = MongoClientSettings.FromConnectionString(mongoClientConnectionString);
